I’ve been testing the Tube Map widget from the page: tflgovuk/forms/12425.aspx but when using it from an HTTPS served page we’re seeing errors (in chrome dev console) that some resources are being loaded using HTTP:

Thanks for looking into this. I’ve attached an image for you. It looks like there’s an attempted redirect happening for those images but Chrome still warns about the mixed content. Maybe it’s due to the 302 rather than a 301 redirect?

Is it possible to get the widget updated so it doesn’t even request the images over HTTP?
